So the greatest common factor 29,644,156 is 1.
Lets's calculate LCM of 68,84,638
2 | 68, 84, 638 |
2 | 34, 42, 319 |
17, 21, 319 |
∴ So the LCM of the given numbers is 2 x 2 x 17 x 21 x 319 = 455532
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/455532
Therefore, the GCF of Fractions 29/68,644/84,156/638 is 1/455532
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 68,84,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,84,638) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(68,84,638) x common factors =2 x 4 = 8
LCM(68,84,638) = ( 68 × 84 × 638 ) / 8
LCM(68,84,638) = 3644256 / 8
LCM(68,84,638) = 455532
